"Sweet Sugar" aka "She-Devils in Chains" (1972) is a classic tropical "Women in Prison" sexploitation film starring gorgeous Phyllis Davis as the titular Sugar. There's even a Pam Grier look-alike as this was most likely inspired by Roger Corman's "The Big Bird Cage" and "Women in Cages".
Clips: Here is the theatrical trailer with the usual over-heated narration: ".38 calibre kittens spitting death as they claw their way to freedom." For the bullwhip bit, you can tell it's dipped in red paint to leave a mark. Flubs: Note how the "stone" guard tower (made of plywood) flies apart when hit by the jeep. Also you can see sparks from an exploding squib charge as a guard is shot in the chest. After the trailer, some rare out takes from a shower scene with a topless Davis (you're welcome).
